Comparative Study
Improved survival and reduced myocardial necrosis with cardiopulmonary bypass reperfusion in a canine model of coronary occlusion and cardiac arrest.
Does cardiopulmonary bypass (CPB) improve resuscitation rates and limit infarct size after cardiac arrest and acute myocardial infarction? ⋯ This pilot study further substantiates the improvement in resuscitation rates obtainable with CPB. CPB may also limit infarct size during the postresuscitation period and requires further study.

The Society for Academic Emergency Medicine model curriculum for medical students and rotating residents was developed over a two-year period. The document was created as a complementary work to the undergraduate Core Content to provide appropriate emphasis, structure, and suggestions on the teaching of emergency medicine core curriculum topics at all levels. ⋯ An educational matrix format was used to enhance flexibility based on the educational level of the learner and the instructional strengths of the teacher, and allowing for incorporation of a problem-based learning format. An outline of document contents and representative samples from each section are included; the entire document is available from SAEM.

To further define the relationship between cardiac output (CO) and end-tidal carbon dioxide tension (ETCO2) at various levels of systemic flow. ⋯ The relationship between CO and ETCO2 is logarithmic. Decreased presentation of CO2 to the lungs is the major, rate-limiting determinant of the ETCO2 during low flow. As the CO increases during resuscitation from shock or cardiac arrest, respiration becomes the rate-limiting controller of the ETCO2 (after the tissue washout of CO2 has occurred). Under such conditions, the ETCO2 provides useful information about the adequacy of ventilation provided that there is little ventilation/perfusion mismatch.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparative trial of three agents in the treatment of acute migraine headache.
A study was conducted to evaluate the relative efficacy of three non-narcotic agents, chloropromazine, lidocaine, and dihydroergotamine, in the treatment of migraine headache in an emergency department setting. ⋯ The relative effectiveness of these three antimigraine therapies appears to favor chloropromazine in measures of headache relief, incidence of headache rebound, and patient satisfaction with therapy.

To study the treatment of moderate-to-severe hypothermia using a combination of core rewarming techniques. ⋯ All patients recovered with this method of core rewarming.
